I'd certainly want to see something in writing that lists all those things that are not included in Texas law. In fact, I'd press the issue to either get something in writing saying they are prohibitted, and a citation of the authority for such prohibition,or a written statement from the Chief Judge that such items are allowed.
There's your <HINT> - judges are allowed to create what are referred to as "local rules" - but those rules are required to be published.
A nicer letter addressed to The Chief Judge asking him/her for a list of items prohinitted in the court building under local rules might get you further along than an angry letter complaining about whether or not your rights were violated. Then, if the items Mr. Smith mentioned to you are not on the list, you can come to court all rigged out with them and show him the letter.
